FIXTURE.

SPEGIFICATION forming part of Letters Patent No. 232,654, datedlseptember 28, 1880.

Application filed July 22, 1880.

To all whom it may concern:

Be it known that I, AI B. SHAW, of Medford, in the county of Middlesex and State of Massachusetts, have invented an Improve. ment in Curtain-Fixtures, of which the following is a specification.

Curtain-fixtures have been made with a spool at the end of the roller, and a ratchet and pawl, and a friction-axle tov the ratchetwheel, so that the curtain can be pulled down and the cord wound upon the spool while the ratchet-Wheel remains stationary.

My present invention relates to a simple and inexpensive frictional device upon the spindle of the ratchet-wheel, and to a novel construction of the collar-plate that is connected with the roller, and forms one end'of the spool upon which the cord is wound.

In the drawings, Figure l is a longitudinal section of the curtain-roller, spool, and bracket. Fig. 2 is a cross-section at the line at m. Fig. 3 is an elevation of the collar-plate. Fig. 4 is a section at the line 3 y, and Fig. 5 is an end view of the curtain-roller.

The roller a is usually of wood, and it is adapted to receivethe curtain or shades, and the end is turned down to form the spool b, around which the cord is wound, as hereinafter set forth.

The collar-plate e is in the form of a flat ring, the central opening of which is of the same size as the spool, and projecting from the side of the collar-plate is a cylindrical flange, i, that corresponds in internal diameter to the external diameter of the roller. I Upon the inner surface of this flanged there are two or more inward-inclined claws, i, that serve to hold the collar-plate upon the roller. These claws are adjacent to openings through the collar-plate, to facilitate the molding of the pattern for casting the collar-plate, and in preparing the end of the wooden roller for the reception of the collar-plate there are notches 5 cut in the Wood, that allow the collar-plate to be freely passed upon the roller, and then the partial rotation of the collar-plate causes the inclined claws to pass into the surface of (No model.)

the roller and hold the collar-plate firmly in place.

The end of the roller a is bored out to receive the spindle f, that projects from the ratchet-Wheel g, and in this spindle f there is a longitudinal slot, throughwhich is passed an S-shaped piece of sheet metal, 13, and this forms a double-ended spring, acting within the roller to produce the friction needed in sustaining the curtain.

There is a groove near the end of the spindle to receive a pin or nail, 3, that prevents the parts drawing apart when in use, and I remark that the bracket '1, that receives the outer end of the spindle, and the pawl m, that catches the teeth of the ratchet-wheel, are made and operate in the same manner as the similar parts in curtain-fixtures that have heretofore been made and used.

When the cord n is drawn upon the curtain is rolled up by the cord rotating the curtain-roller. When the cord is held at such an angle as to lift the pawl the curtain can be lowered, as heretofore, and when the curtain is drawn upon the roller a and spool 15 are revolved and the cord rolled upon the spool, as heretofore; but the peculiar S-shaped spring t, that is within the curtain-roller, applies friction to hold the curtain, and this spring is very cheap in its construction, reliable in its operation, and not liable to injure the wooden roller, upon which it acts.

The end of the cord passes through a hole, 4, in the collar-plate e, and is secured by a knot, as usual.

I am aware that a spring has been introduced between the forked ends of the axle of -a curtain-fixture to produce friction against the inner surface of the curtain-roller. In this case, if the spring becomes displaced, its edges may scrape or cut the woodof the roller and render the fixture useless. V

In my improvement the metal axle has only a slot or mortise through it, and the S-shaped spring of sheet metal is passed endwise into the same and acts expansively against the interior surface of the wood roller. It cannot becomeinisplaced or injure the wood, and it ing a cylindrical flange to surround the cur- I0 is cheap, and easily made-and applied. tain-roller and inclined claws upon the inte- I claim as my inventionrior of 'the cylindrical flange, as set forth. 1.
